    In this study; the short films and videos taking part in National Instructional Short Film and Video Contest held in Kırıkkale University are evaluated in terms of some variables such as; the departments of the teacher candidates, whether the product is video or film. Quantitative methods were used in the study. The research method of the study is descriptive method. Quantitative data was obtained by using Short Movie and Video Assessment Scale prepared by the researchers the rubric consists of four sub-titles, the usage of audio-visual elements, focusing the aims and objectives, selection and presentation of the content, taking target group into consideration. There are 20 items in the scale. Each item can be graded between 1 -10 and the arithmetic mean of the items gives the total point of the films. All of the 47 films taking part in the contest were evaluated. According to the results, these films and videos are graded as average. Besides this, there are no significant difference between instructional short film and videos in terms of technical aspects, content, aims and objectives; but for the target group/audience, videos are graded as more effective than short films. In addition, the scores of the instructional short films and videos prepared by the students in Department of Computer and Instructional Technologies are considerably higher than the other departments’ scoresBu çalışmada ulusal eğitsel kısa film ve video yarışmasına katılan eserler, öğretmen adaylarının öğrenim gördükleri bölüm, eserlerin film ya da video özelliği taşıma durumu gibi değişkenler bağlamında değerlendirilmiştir. Araştırmada betimsel yöntem kullanılmıştır. Araştırmacılar tarafından geliştirilen eğitsel kısa film ve video değerlendirme ölçeği ile nicel veriler elde edilmiştir. Geliştirilen değerlendirme ölçeği; görsel ve işitsel öğelerin kullanımı, hedefe odaklanma, içerik seçimi ve sunumu ile hedef kitleyi dikkate alma olarak dört başlık halinde yirmi madde olarak hazırlanmış ve her bir maddeye 1 ile 10 arasında verilen puanların aritmetik ortalaması alınarak kısa film ve videonun başarı puanı belirlenmiştir. Yarışmaya katılan 47 eserin tamamı değerlendirmeye alınmıştır. Yapılan değerlendirme, eğitsel film ve videolar arasında görsel ve işitsel ögelerin kullanımı, hedefe odaklanma, içerik seçimi ve sunumu alt boyutlarında anlamlı düzeyde fark olmadığını, hedef kitleyi dikkate alma alt boyutunda ise eğitsel videoların daha etkili olduğunu göstermiştir. Ayrıca Bilgisayar ve Öğretim Teknolojisi bölümü öğrencileri tarafından hazırlanan film ve videoların değerlendirme puanlarının anlamlı olarak daha yüksek olduğu bulunmuştur

    PURPOSEThe clinical management of high-risk lesions using image-guided biopsy is challenging. This study aimed to evaluate the rates at which such lesions were upgraded to malignancy and identify possible predictive factors for upgrading high-risk lesions.METHODSThis retrospective multicenter analysis included 1.343 patients diagnosed with high-risk lesions using an image-guided core needle or vacuum-assisted biopsy (VAB). Only patients managed using an excisional biopsy or with at least one year of documented radiological follow-up were included. For each, the Breast Imaging Reporting and Data System (BI-RADS) category, number of samples, needle thickness, and lesion size were correlated with malignancy upgrade rates in different histologic subtypes. Pearson’s chi-squared test, the Fisher–Freeman–Halton test, and Fisher’s exact test were used for the statistical analyses.RESULTSThe overall upgrade rate was 20.6%, with the highest rates in the subtypes of intraductal papilloma (IP) with atypia (44.7%; 55/123), followed by atypical ductal hyperplasia (ADH) (38.4%; 144/375), lobular neoplasia (LN) (12.7%; 7/55), papilloma without atypia (9.4%; 58/611), flat epithelial atypia (FEA) (8.7%; 10/114), and radial scars (RSs) (4.6%; 3/65). There was a significant relationship between the upgrade rate and BI-RADS category, number of samples, and lesion size Lesion size was the most predictive factor for an upgrade in all subtypes.CONCLUSIONADH and atypical IP showed considerable upgrade rates to malignancy, requiring surgical excision. The LN, IP without atypia, pure FEA, and RS subtypes showed lower malignancy rates when the BI-RADS category was lower and in smaller lesions that had been adequately sampled using VAB. After being discussed in a multidisciplinary meeting, these cases could be managed with follow-up instead of excision
